Title: Undercarriage arrangement for normally static articles
Inventor: DOOLEY JOSEPH
IPC: F16M11/42
Filed: 1986-12-17
Granted: 1991-02-05
Abstract: ABSTRACT "An undercarriage arrangement for normally static articles"     An undercarriage arrangement for normally static objects such as work-benches comprises at least one pair of wheels or rollers which are mounted for rotation on at least one support member pivotably mountable on the object.   A spring biassing arrangement is provided, one end of the spring being pivotally mounted on the support member and the other end thereof being attached to means mounted on the object.   The means may comprise a pivotal lever or projections.  In either case, the second end of the spring can be displaced between two or more pre-selected positions with the proviso that at least two of the pre-selected positions are disposed on opposed sides of a vertical plane passing through the pivot axis For the at least one support member.     The two end positions for the second end of the spring are so selected that, in one position, the wheels are located generally above the lowermost portion of the object and, in the other position, are located generally below the lowermost portion of the object.  The displace-ment of the second end of the spring thus enables  any static abject to which the arrangement is fitted to be transposed from a conventional static mode into a transportation mode and, once transported, returned to its conventional static mode.

Filed: 1987-08-14
Granted: 1992-03-31
Abstract: ABSTRACT OF THE DISCLOSURE     The invention discloses a method and apparatus For producing foam-filled stud walls.  The apparatus has a main frame, including a substantially vertical backplate against which the sheathing bears, a carrier unit moveable vertically on the main frame, and a dam carried on the carrier unit parallel to the backplate, moveable towards and away from the backplate.  Hydraulic actuators are located between the carrier unit and main frame, and between the dam and the carrier unit, to hold the dam against the stud wall when the stud wall is positioned with its sheathing against the backplate, and to move the carrier unit and thus the dam vertically while it is so held against the stud wall.  The method includes introducing at least a portion of an unfilled stud wall between a substantially vertical backplate and a substantially vertical dam, with the sheathing against the backplate; moving the dam against the bottom portion of the open side of the stud wall; introducing foam between the backplate and the dam to fill the stud wall therebetween; moving the dam upwardly;  introducing additional foam to fill a higher portion of the stud wall;  repeating the two preceding steps on to completion of Filling;  moving the dam away from the stud wall; and advancing the filled portion of the stud wall from between the backplate and dam.

Title: Word synchronizer

Granted: 1991-09-17
Abstract: "Word Synchronizer"               ABSTRACT OF THE DISCLOSURE         For establishing word synchronization between a data bit stream of N-bit words and the timing of syndrome calculation, a count value is incremented in response to the bit timing of the words and generating a hunting pulse for every count of N bits and a load timing pulse at every count of C bits.  Syndrome calculation is performed on the N-bit words in response to the hunting pulse to derive a syndrome when each of the N-bit words is out of synchronization with the timing of the calculation.  The syndrome is latched for a word interval and a first enabling signal is generated in response to the latching of the syndrome.  Syndrome generating words are counted to generate a second enabling signal when the count provides a valid indication that the word timing of the calculation is out of sync with the data bit stream. A copy of the hunting pulse is generated and delayed for a period of M bits when the first and second enabling signals are simultaneously present to cause syndrome calculation to be performed on the N-bit words, where the N and M integers are relatively prime and the integer C is smaller than integer M and greater than unity.  The point of initialization is shifted for each syndrome calculation from one bit to another in search of the beginning of a word.  Because of the "relatively prime" relationship of the integers N and M, all the bits of incoming data bit stream are examined in the search.

Abstract: "ULTRASONIC METHOD FOR MEASURING INTERNAL contact PRESSURE BETWEEN MATING SOLID PARTS SEPARATED BY A LIQUID FILM"     ABSTRACT OF THE DISCLOSURE           A  method is provided for directly measuring the contact pressure on the mating interfaces of two solids undergoing compression where the interfacial region contains an entrapped film of liquid.  An acoustic pulse is directed at either interface.  A reference amplitude of the acoustic pulse reflected from the interface is measured as it bears initial contact pressure.  A second "loaded" amplitude of the acoustic pulse reflected from the interface is measured when the interface is bearing a different contact pressure.  A measure indicative of the change in contact pressure is computed from the ratio of the reference and loaded amplitude measurements by correlation with a calibration curve.

 X being the molar percentage of trifluoroethylene in the macromolecular chains and Y being the weight percentage of all the macromolecular chains whose trifluoroethylene content is higher than or equal to X. This copolymer is obtained by copolymerisation in aqueous suspension by reaction, in a first step, of a mixture of vinylidene fluoride and of trifluoroethylene in molar proportions of vinylidene fluoride of between 67 and 54% to 33 to 46% of trifluoroethylene and, in a second step, by progressive addition of vinylidene fluoride to the reaction mixture in proportions such that the molar quantity of added vinylidene fluoride represents 145 to 180% of the number of moles of initial vinylidene fluoride.

Granted: 1993-12-14
Abstract: ABSTRACT OF THE DISCLOSURE      There is disclosed a metatarsal pad structured with relation to the foot for which it is intended so that it bridges across the width of the five metatarsal bones which extend between the ankle and the toes of the foot; a configuration of the pad at the front is such that each metatarsal is supported just posteriorly of the head thereof and with a height to raise the heads of the metatarsals from weight bearing and transfer of the weight over a larger area. The front of the pad is characterized by a radius of curvature of about 3/16 of an inch in the vertical plane and the frontal outline in the horizontal plane is preferably convex in the central portion while being slightly concave on either side thereof; this conforms to the shape of volar surface of the metatarsal as it develops the head of each metatarsal.          The alternate concave and convex frontal outlines follow a line just posterior to the head of the first metatarsal and progressing laterally just behind the head of each subsequent metatarsal. The pads are asymmetric and different shapes are provided for the left and the right foot. A minimum of about five sizes are provided for adult foot sizes. The pads may be formed of room temperature curing urethane elastomer or injection molded latex or other suitable material, preferably with flexibility, resilience and relatively low compressibility. It is contemplated that the pads will be fitted in the shoe by properly trained persons for maximum benefit in reducing trauma to the heads of the metatarsal that cause callosities and other problems.

Filed: 1989-05-23
Granted: 1997-01-21
Abstract: A composite membrane comprises an inorganic support having interstices and porous inorganic films of sintered non-metallic particles carried by the support and bridging the interstices thereof.   The support is preferably a woven metal mesh, with the films substantially coplanar with the support.   The films may be formed by applying a suspenion of refractory particles in a polymer solution to bridge the interstices of the support, and heating the films to partly sinter the particles.   Since the films are in compression at ambient temperature, any cracks that may be formed by damage to the composite membrane tend not to propagate.
